A robust mixed-Eulerian-Lagrangian modeling is presented for the simulation of violent bubble motion, which is characterized by implementing a hybrid surface interpolation for calculating the material velocity. A linear averaging approximation is deployed for the parts of the surface where the change of the surface normal within the element size is not small, and a polynomial scheme coupled with the weighted moving least squares method for the rest of the surface. Solid angles on the free… 
Numerical investigation of three-dimensional bubble dynamics
This work is devoted to a numerical investigation of three-dimensional gas-vapor bubble dynamics. Bubble oscillations in ambient unbounded fluid and interaction of the bubble with different inclined
Bubble dynamics in a compressible liquid in contact with a rigid boundary
The computations correlate well with experiments for both the first and second cycles of oscillation, and the wall effects are modelled using the imaging method, which shows clear potential to damage the boundary.
The motion of a 3D toroidal bubble and its interaction with a free surface near an inclined boundary
The numerical modelling of 3D toroidal bubble dynamics is a challenging problem due to the complex topological transition of the flow domain, and physical and numerical instabilities, associated with
Vortex ring modelling of toroidal bubbles
During the collapse of a bubble near a surface, a high-speed liquid jet often forms and subsequently impacts upon the opposite bubble surface. The jet impact transforms the originally
Numerical and Experimental Study of Bubble Impact on a Solid Wall
The dynamic characteristics of a bubble initially very close to a rigid wall, or with a very narrow gap, are different from those of a bubble away from the wall. Especially at the contraction stage,
Numerical investigation of bubble dynamics at a corner
This paper is concerned with bubble dynamics at a corner formed by two flat rigid boundaries associated with applications in ultrasonic cleaning and cavitation damage. This phenomenon is modeled
Bubble collapse in compressible fluids using a spectral element marker particle method. Part 1. Newtonian fluids
This paper is concerned with the development of a high‐order numerical scheme for the modelling of two‐phase Newtonian flows. The companion paper, herein referred to as Part 2, extends the scheme to
Non-spherical bubble dynamics of underwater explosions in a compressible fluid
This paper is concerned with the bubble dynamics of underwater explosion in a compressible liquid flow whose Mach number, based on characteristic liquid velocities, is O(10−1). We will study this


Three-Dimensional Computation of Bubbles Near a Free Surface
A new boundary element model for simulating the interaction of one or more bubbles and a free surface is described. An important feature of this model is the utilization of a nine-noded Lagrangian
Strong interaction between a buoyancy bubble and a free surface
The growth and collapse of buoyant vapor bubbles close to a free surface in an inviscid incompressible fluid is investigated in this paper. The strong interaction between the deforming bubble and the
The final stage of the collapse of a cavitation bubble close to a rigid boundary
The final stage of the collapse of a laser-produced cavitation bubble close to a rigid boundary is studied both experimentally and theoretically. The temporal evolution of the liquid jet developed
A numerical investigation of non-spherical rebounding bubbles
The motion of buoyant transient cavities with non-condensible contents is investigated numerically using a boundary-integral method. The bubble contents are described by an adiabatic gas law. Motion
3D Impact and Toroidal Bubbles
Abstract A three-dimensional model of collapsing bubble with jet formation and impact is presented in this paper. The strong instabilities of the jetting process, impact, and toroidal bubble rebound
On the nonspherical collapse and rebound of a cavitation bubble
The behavior of a cavitation bubble adjacent to a rigid wall is studied numerically with the boundary integral method described in Zhang, Duncan, and Chahine [J. Fluid Mech. 257, 147 (1993)]. In the
Transient cavities near boundaries Part 2. Free surface
Calculations of the growth and collapse of transient vapour cavities near a free surface when buoyancy forces may be important are made using the boundary-integral method described in Part 1. Bubble

The computational study is extended to model cavitation bubble growth and collapse phases in a forward stagnation point flow as a model of reattachment of a boundary layer; a region where severe cavitation damage is often observed.
Transient cavities near boundaries. Part 1. Rigid boundary
The growth and collapse of transient vapour cavities near a rigid boundary in the presence of buoyancy forces and an incident stagnation-point flow are modelled via a boundary-integral method. Bubble
